Red Snow in Tuscany, Italy
Poets involved
What happened
In 1816, the year without a summer caused by the Mount Tambora eruption, Tuscany in Italy experienced a snow of a brick-red hue. This red snow, likely caused by Saharan dust or volcanic ash mixed with precipitation, astonished local populations already reeling from climatic anomalies. The event was documented by contemporary naturalists and added to the lore of blood snow.
Literary impact
The red snow of 1816 coincided with the Romantic era's fascination with apocalyptic and sublime nature. Poets like Lord Byron and Mary Shelley, who were in Switzerland during that dark summer, may have been influenced by reports of such strange weather. The image of red snow appears in later Romantic and Victorian poetry as a symbol of nature's otherworldly beauty.
